Ceiling effect

In Hannah case the experimental group and the control group was pretty much not significantly different because both groups were already good at the sport. Her experiment couldnt function properly because there is no accuracy to the test since both groups perform well, this is known as a ceiling effect

The term ceiling effect is a measurement limitation that occurs when the highest possible score or close to the highest score on a test or measurement instrument is reached, thereby decreasing the likelihood that the testing instrument has accurately measured the intended group.
